When will plans for iPhone 6s come out?

I know you can pre order in 4 hours, but what about actual monthly plans, that generally have a contract for 24 months? When do those types of plans usually come out?

Do you mean installment plans, i.e pay monthly for the phone? They should be the same as before.Depending on carrier and phone size; it can be anywhere from $20.00 - $40.00 a month. If you go into a cell phone carrier shop they should have the monthly rates.

Preorders start at 3:01am ET tomorrow which is 13 hours 23 minutes as I type this, which would have made it 16 hours 23 minutes based on how long the question was posted prior to me seeing it.

Anyway you should be able see those on the carrier's respective websites & shouldn't be much if any different from the ones for the iPhone 6.
